Although you might be a complete beginner, you have probably heard about two most commonly used development languages called JavaScript And TypeScript. But since you are a beginner, you might be a bit confused and overwhelmed by the differences between the two, particularly the benefits you can gain from utilizing TypeScript.

And if you are in this situation, this article might help you understand those differences. The text below is going to feature a beginner’s guide for learning the main advantages you can gain from choosing to use TypeScript rather than JavaScript. Let’s take a closer look:

TypeScript: What is it And Why Should You Use it

Before we write about the benefits that you could gain, it is important to learn what the programming language actually is and why you should utilize it. TypeScript – seen below as TS – basically has the same functions as JavaScript – seen below as JS – however, it does have new and improved features that can help you quite a lot. This means that they’ll both do and finish the same task, but TS will do much more for you.

Now, you might be wondering – why should I choose TS? Well, Java is fast, easy to utilize, and simple. It is also a language that can be dynamically transcribed, but since it is flexible, you can easily lose your structure when creating something. But, with TS, it will have all the features that Java has, however, it has a structure, and it will check your typing. If there is a need for the writing to be dynamic, TS will easily and quickly correct it to JS.

This implies that you’ll gain all the features offered by JS, but you’ll also have some new, additional features that will help you with your tasks. If you are interested in finding out what other things you should learn, if you’re a beginner at coding, check out this post for more information.

The Benefits You Can Gain

There are various advantages that you could gain from choosing to utilize TS, and some of the most important ones are:

1. You’ll Be Able to Target Several Browsers

If you want to target several browsers and if you are trying to utilize all the features Java offers, you won’t need to use other building tools that can help you. By utilizing TS, all you’ll need to do is write your initial code, opt for a specific browser that you want to target, and the rest will be finished by TS.

2. It Could Be Utilized For Making Large Apps

When you are making a large application or an item that you want to use for structuring the entire system, you should utilize the TS benefits. By doing so, you’ll be able to create an app in an easy way, as well as one that won’t need a lot of maintenance since it will have fewer lags and bugs.

If you take a look at Java, you’ll gain some critical issues from the beginning including the lack of sign hinting/casting, there will be no object-oriented programming, there will be no way for you to create a stable base structure for your project, and the new JS API’s won’t be available in cross platforms.

3. You’ll Gain Type Hinting/Casting

The thing that most people love about TS? It offers character hinting and casting, which means that a value is assigned to every specific number. Next, the program will emphasize an error while immediately developing and resolving the problem before it is even deployed. Without this, it would take much longer to find where you made an error and correct it. But with TS, you won’t have to worry about such issues.

4. It is Predictable

As mentioned earlier, all you’ll need to do is type in your initial code and the program will do the rest instead of you. What does this mean? Well, it means that everything will stay as you initially defined it. If something is declared as a string, it will remain a string. All of this will improve the chances of the functions and features working properly, as you initially intended them to work.

5. You Can Get Advice From Millions of People

TS is an open-source language and its community of users is constantly growing. Since millions of programmers and developers use it, you’ll be able to get advice from them by joining their online communities and asking for assistance. Most of them will be thrilled to help you, especially since they do not want this particular technology to be abandoned.

So, What Are Some Drawbacks?

Like everything else in life, there are some drawbacks to using TypeScript. Luckily for all of us, there are more advantages than disadvantages to this program, however, we should mention what issues you might come across. The drawbacks that you will notice include:

1. You’ll Need Time to Learn it

The very first thing that you should know is that it is not difficult to learn how to use TS, but, you should also know that it will take you a lot of time and effort to do so. Although it is similar to JavaScript, you’ll still need to go through various books, guides, and online tutorials that will all be useful for you.

2. You’ll Want to Transpile it Before Running

Browsers cannot really interpret the code of TS, which means that you’ll need to transpile it to Java before you run it. But, although it is a drawback, the process is automated, which means that it won’t take a lot of time to accomplish this. In fact, it is not a drawback, but it is still worth mentioning.


As you were able to learn, there are various differences, as well as advantages that you can gain from using TypeScript rather than JavaScript. Not only will it correct spelling errors, but it will also allow you to create larger applications and it is also predictable, meaning that you’ll be able to efficiently finish your project.

So, now that you know what you can gain, you may not want to lose any more of your time. Instead, you should open up your browser and start searching for some online tutorials and guides that will help you understand and learn TypeScript in an easy and time-efficient way.
